Police have launched an air and sea search for two surf skiers who have gone missing in Moreton Bay, off Stradbroke Island.
The men, aged in their mid-to-late 20s, left Dunwich, on the western side of the island, at 10:30am on Saturday.
They were heading to Cylinder Beach on the northern side of the island but did not arrive.
A search involving water police, volunteer marine rescue, a fixed-wing jet and a rescue helicopter is expected to continue into Saturday night.
Police say the two men are on surf skis — one orange and black, the other a white Epic V8 Pro.
They do not have any food with them.
Anyone who has spotted the missing pair is urged to contact authorities.
